Fan whistle apparently confuses Seahawks on blocked punt (Video)

The Seahawks 12th Man came out in force for Sunday night’s matchup against San Francisco. But instead of aiding the team, one fan possibly hurt it.

After being forced to punt on their first offensive possession, 49ers safety Craigh Dahl blocked John Ryan’s punt. Before the snap, Seahawks players appeared confused, leading to shoddy blocking on the play. It looks like that confusion was a reaction to a stray whistle, which apparently sounded from within the crowd.

You can actually here the whistle sound before the snap in this video. Listen closely:
